"A critical vulnerability exists in Adobe Flash Player 10.2.152.33 and
earlier versions (Adobe Flash Player 10.2.154.18 and earlier for Chrome
users) for Windows, Macintosh, Linux and Solaris operating systems,
Adobe Flash Player 10.1.106.16 and earlier versions for Android, and the
Authplay.dll component that ships with Adobe Reader and Acrobat X
(10.0.1) and earlier 10.x and 9.x versions of Reader and Acrobat for
Windows and Macintosh operating systems.

This vulnerability (CVE-2011-0609) could cause a crash and potentially
allow an attacker to take control of the affected system. There are
reports that this vulnerability is being exploited in the wild in
targeted attacks via a Flash (.swf) file embedded in a Microsoft Excel
(.xls) file delivered as an email attachment. At this time, Adobe is not
aware of attacks targeting Adobe Reader and Acrobat. Adobe Reader X
Protected Mode mitigations would prevent an exploit of this kind from
executing."

It is recommended that users update to the latest version of this software.
